SFC6400A/SFC1450A Synthesized Frequency Upconverter Operation

Figure 3-2. RCU101 Typical Interconnection with SFC Upconverters
After all of the converters have been programmed, the back up converter is then set into a “Learn
Mode.” The backup poles each converter on a continuous basis and learns and stores the settings
of each converter. Because the switch modules are on a common protection bus, each converter
knows the address (position in the rack), and the fault status of all of the converters in the rack. In
the event of multiple failures, the highest priority converter that fails is backed up first.
The chain switch provides the primary through path between the converter RF output and the output
of the switch module without being powered. It is provided with redundant power from all converters
connected in the chain. In the event that a Upconverter needs to be replaced, the Chain Switching
Module can be removed from the back of the converter and left in place without breaking the
interconnections to adjacent converters in the chain.
